Stabilized copolyetheresters

ABSTRACT

thermoplastic copolyetherester elastomers improved by incorporating into the copolyetherester effective concentrations of N,N&#39;-hexamethylenebis(3,5-di-tert-butyl-4-hydroxyhydrocinnamamide) and N,N&#39;-trimethylenebis(3,5-di-tert-butyl-4-hydroxyhydrocinnamamide) to yield non-discoloring compositions having outstanding heat stability and little or no tendency to bloom.
